Can I take Niuhuang Jiedu Tablets for lip sores caused by excessive internal heat ("shanghuo")?

Generally speaking, whether one can take Niuhuang Jiedu Tablets for lip blisters caused by "heatiness" depends on the specific pattern of the condition. The tablets may be taken if the blisters are due to external wind-heat or excessive stomach fire, but are not suitable for cases caused by yin deficiency with hyperactive fire. Detailed analysis is as follows:

Lip blisters triggered by external wind-heat or excessive stomach fire are often accompanied by symptoms such as redness, swelling, pain, dry and bitter mouth, and sore throat. Niuhuang Jiedu Tablets contain ingredients like bezoar, realgar, and gypsum, which have the effect of clearing heat and detoxifying. They can effectively alleviate excessive internal heat, helping to reduce inflammation and pain at the blister site.

In cases of lip blisters caused by yin deficiency with hyperactive fire, the blisters typically have thin walls and tend to recur frequently, accompanied by symptoms such as heat in the palms, soles, and chest, dry mouth with little desire to drink. As Niuhuang Jiedu Tablets are cold in nature, taking them in such conditions may further damage body fluids and worsen discomfort; therefore, their use is not recommended.

In daily life, it's important to keep the lips clean and avoid squeezing the blisters to prevent infection. Avoid spicy, fried, and other heat-inducing foods. Instead, consume more heat-clearing and dampness-resolving foods such as mung bean soup and winter melon, and ensure adequate hydration. Additionally, maintain sufficient sleep, avoid staying up late, and minimize triggers of "heatiness."
